I'm not clear on exactly what difficulties you are having setting up the edit user form as the document explains the step, however instead of an edit post form it will just be a user form.
Could you provide a bit more details on the difficulties you are having ?
It is actually working fine, it was just that you didn't add the edit user link to the view as well as the slug to call the view to the page was incorrect.
I had a look through the documentation and wondered if it would be possible through Toolset to add a tick box next to users to allow us to then send an email to the selected users?
